How to Use the Ports
The gateway terminal port(s) can be used to:
 Accept dialed phone connections and turn them into TCP/IP network connections to
remote hosts (outgoing connections) optionally using SSL security
 Accept TCP/IP network connections from remote hosts (incoming connections) and
make a phone connection to an attached device.
The gateway serial port(s) can be used to:
 Emulate a dial-up modem connection over TCP/IP (via Modem Emulation)
optionally using SSL security
 Initiate TCP/IP network connections to remote hosts (outgoing connections)
optionally using SSL security
 Accept TCP/IP network connections from remote hosts (incoming connections)
The following sections describe each of these configurations in more detail.
You will need to configure the desired service and set up the proper serial parameters for
your device. For more information on configuring the serial settings, see the section entitled
Serial Settings.
Configuring Dial to IP on Terminal Ports
The gateway terminal ports can be configured to accept an incoming phone call, answer it
with it’s internal modem, initiate a TCP connection to a remote host, and then route all data
over this connection. This connection is configured to match the protocol required by the
host. It is generally used to connect a terminal with a built-in modem to a network-based
host.
To configure a terminal port for outgoing TCP network connections:
1. Configure the correct parameters for the terminal port (see Serial Settings)
2. Configure phone number to host/port pair translation (see Phone Number
Translation)
3. Configure the protocol to use for the target host (see Protocol Settings)
